Part of the Sentron ED frame family, the Siemens CED63B015L is a 3-pole, 15A molded case circuit breaker for commercial applications. It features thermal-magnetic trip technology with fixed long-time and instantaneous functions. This unit-mount breaker installs into Siemens P2 and P3 panelboards, switchboards, and motor control centers. As a current-limiting device, it delivers a 200kAIC rating at 480V, minimizing let-through energy to protect equipment. Line and load lugs are included.

6 answers
What does the L suffix mean in the CED63B015L catalog number?
The L suffix indicates that the circuit breaker is factory-supplied with both line and load side lugs installed. These lugs accept 14 to 10 AWG copper or 12 to 10 AWG aluminum conductors.
What equipment is compatible with the CED63B015L breaker?
This ED frame breaker is a unit mount, feed-thru device designed for installation in Siemens P2 and P3 panelboards, switchboards, motor control centers, and individual enclosures.
Can the CED63B015L be reverse fed?
Yes. Siemens ED frame circuit breakers feature non-interchangeable trip units and are suitable for reverse feed applications.
How does the current limiting feature affect the breaker ratings?
As a current limiting device, it clears faults in a fraction of a cycle to minimize let-through energy. This provides a high interrupting capacity of 200kA at 480VAC and 100kA at 600VAC, offering enhanced protection for downstream equipment.
Is this breaker suitable for direct current applications?
Yes, the thermal magnetic trip unit is rated for DC systems up to 500VDC. It delivers an interrupting capacity of 50kA at 250VDC and 30kA at 500VDC.
Are the trip settings adjustable on the CED63B015L?
No. This breaker features a fixed thermal and fixed magnetic trip unit with standard long-time and instantaneous protection functions.
